To achieve this objective, a 24 months randomized trial will be implemented SPOT's community site. Participants who present for HIV testing will be randomized between the two conditions, MIC and SC, alternated at a ratio of 1/1 (experimental condition: MIC offered by a community worker; control condition: SC offered by a nurse). Outcome measures will be collected by means of questionnaires. Four measurement times are planned. A baseline questionnaire will be administered prior to pre-test counseling at the start of the initial visit. Outcome measures will be assessed at baseline (T0), and in follow-up questionnaires administered after post-test counseling at the end of the initial visit (T1), at 3 months after the initial visit (T2) and at 6 months after the initial visit (T3). Target enrolment at T0 is 900, for a final sample of 508 participants at T3, representing 254 participants per group (MIC, SC). Mechanisms will be put in place to ensure the integrity of both MIC and SC interventions as well as to retain participants and involve community members in the research process.
